Length of head above 2/7, of caudal 2/11, height of body 4/7 of the total length. Eyes — diameter 

 4/13 of the length of head, 1 diameter fi-om the end of snout, and also apart. Preopercle finely serrated. 

 Teeth — brush-like. Fins — dorsal spines of moderate strength, soft portions of both dorsal and anal fins angular. 

 Pectoral as long as the head behind the anterior nostril : ventral reaches to the anal : second anal spine strono-er 

 but of equal length to the third. Colours — snout vnth a black band : a dark ocular one descends through the 

 eye over the interoperole to the chest : numerous fine dark lines descend downwards and forwards from the first 

 half of the dorsal fin to the middle of the body, whilst in the posterior half of the body there are others havinc a 

 direction downwards and backwards. Dorsal and anal fins dark, having a black margin and a light external 

 edge, the dark line is continued over the posterior third of the body : there is another dark line over the free 

 portion of the tail, and a dark semilimar mark on the caudal fin. Ventral darkest in its centre. 



Amongst Sir Walter EUiot's drawings exists a figure of this species marked Eunnadee or Kalloodi : a 

 second labelled September, 1848, shows the red bands across the snout, this is the variety. No. 83, figured by 

 Russell and identical with C. decussatus, C. and V. 



Habitat. — Red Sea, those of India to the Malay Archipelago, attaining at least 10 inches in length. The 

 specimen figm-cd is Hfe-size from one captui-ed at the Andamans.

Length of head about one fourth, of caudal from 6| to one sixth, height of body 1| of the total length. 

 Eyes — diameter .3/10 of the length of head, Ij diameters from the end of snout, and also apart. Snout rather 

 produced and pointed. The maxilla reaches to below the front nostril. Preopercle finely serrated, most strongly 

 so at its angle. Teeth — brush-like. Fins — dorsal spines of moderate strength, the interspinous memlsrane 

 deeply notched : soft portions of the dorsal and anal obtusely angular : pectoral as long as the head behind the 

 angle of the mouth : ventral nearly reaching the anal : second anal spine equals the length of the third : caudal 

 rounded. Colours — a black ocular band ha'^'ing white edges descends to the angle of the interopercle. Numerous 

 dark bands pass downwards and forwards to the centre of the depth of the body, where others pass backwards. 

 Dorsal and anal fins margined with black. Two black vertical bands on the caudal, the anterior of which is 

 concave. 



Habitat. — From the Red Sea, through those of India to Polynesia.

Length of head 4J, of caudal 6|, height of body 2j of the total length. Eyes — diameter Sf of the 

 length of the head, Ij diameters from end of snout and also apart. The maxilla reaches to about half way 

 below the front edge of the orbit. Preopercle entire, its angle very oblique. Teeth — bi'ush-like. Fins — 

 dorsal spines of moderate strength, increasing in length to the fifth, the soft portion of the fin as high as the 

 spinous and rounded posteriorly : ventral spine strong, as long as the head excluding the snout : caudal cut 

 nearly square : anal spines of moderate strength but long, the thii'd rather the longest exceeding the highest of 

 the dorsal by nearly one foiu-th, soft portion of the fin similar to that of the dorsal. Colours — head and anterior 

 two-thirds of the body lavender, its posterior third yellow : interorbital space yellow : a narrow dark white- 

 edged band commences a little in front of the dorsal fin, then ceases, but reappears a little above the eye, 

 through which it descends and passes down the preopercle to a little in front of its angle. Anterior two-thirds 

 of the body with narrow black vertical bands, which form an angle at the middle of the body directed forwards. 

 A narrow dark intramarginal line having a white outer edge exists on both the dorsal and anal fins : a narrow 

 dark vertical band in the last third of the caudal, followed by a rather wider yellow one, whilst externally the 

 fin is grey. 



In Garrett's " Fische d. Sudsee," the formula given is D. -i-l, A. x\-, and if it is the same species the 

 figure is not exact.
